Superdrol timing at 20mg

How important is the preworkout dose of Superdrol. I wake up at 7, work out at 12:30. Any body have any input on dosage time now that I'm up to 20mg? I know that a lot of people dose the second dose 8 hours after the first, but if i wake and take one, should my second dose be at 11 or closer to like 3?
